Possibilities of human eye color?

Question

Just for fun, I've been checking out various eye color calculators (those that calculate, for example, what colors my children's eyes would be based on my own eye color and that of my mate). I'm brown-eyed (and come from two brown-eye parents), and I've always been of the belief that (regardless of my mate's eye color) my genetic make-up would not allow me to produce a blue-eyed child. But at least two of these calculators have displayed a 1/6 possibility for me to have a blue-eyed child. I'm confused... is it possible for a person like myself, being brown-eyed and coming from two brown-eyed parents, to have a blue-eyed baby?!?

Answer 1

Yes it is possible. Just because your parents are brown eyed doesnt mean that they do not carry the gene for blue eyes, would would simply be recessive to the dominant allele for brown eyes. You could simply have inherited a dominant brown allele and a recessive blue allele from your parents. Your partner could be the same, only if your partner carried two dominant brown alleles would your child be brown eyed. You should probably find out your genetic make up to determine it correctly first.

Answer 2

If you are heterozygous (Bb) for brown eye color then it will be possible to have a non-brown eyed child; not so if you are pure/homozygous (BB) for this trait. The same goes for your mate. By the way , since around 64 eye color variations in humans have been identified, offspring eye color can vary anywhere between nearly black to blue; or to an extreme case, albino (pink). Eye color predictions are not easily done by conventional genetic (Punnett square) crosses.

Answer 3

Yes. Although your phenotype may not reflect it, your ancestors may have had blue eyes. This will mean that with the right eye color genes of your mate (sorry for the lack of a better word), you may be able to have a blue-eyed child.

Answer 4

you and your husband could both be Bb (brown dominant, but with a blue recessive gene), but then I think you would have a 1/4 probability of a blue eyed child, not 1/6.

Answer 5

yes, i think it's possible to have a blue eyes baby only if you have a grandfather or a grandmother with blue eyes therefore your eyes aren't true brown eyes but the gene of the brown eyes is predominant.so if you marry a mate who has also mixed eyesthe probability of having a baby with a blue eyes will be small but ,of course, presents.

Answer 6

Possible! :)
Your parents might be both Bb (Brown being dominant), so you also might be Bb!
Then marry a guy with blue eyes (bb).

Using Punett Square, Bb x bb can produce
1/2 Bb : 1/2 bb
that means, 1/2 brown and 1/2 blue!! :)

Answer 7

one in a million

i checked out the same site a while back b/c my guy's family has blue eyes while my mom has brown and my dad has green. All 5 kids got my mom's brown eyes . . .

brown is a more dominant eye color.

it's not REALLY one in a million but it really would be a slim chance that your child would have blue eyes. You never know though . . .

:)

Answer 8

Yes. One of your two parents could have recesive blue eye gene, and passed it on to you, thus the dominante brown eye gene showing up. If your husband has the same, where, he too, has brown eye dominate and blue eye resesive, and perchance, you both happen to donate the recesive gene, your child can end up with blue eyes.

Answer 9

i think of dark brown is the main trouble-free eye color in the international because of the fact very almost each Asian in the international certainly has dark brown eyes (in spite of if dark brown eyes generally seem to be black). And China takes approximately 20% (a million.3 billion) of the international's inhabitants so i assume black is definitely trouble-free. And the colour of our eyes depend upon the quantity and kind of pigment that are modern-day. i assume Caucasians in basic terms have all the forms of pigment modern-day of their genes.

Answer 10

not usually but can happen the baby's loot n features can depend on upto 3 gen...
